This is what a good Auvik map looks like

This map has a mix of blue and black wires, which indicates Auvik is successfully reading data for Layers 1, 2, and 3. If you have managed Wi-Fi controllers and access points, you may also see dotted wires between APs and endpoints. The correct symbol is showing for most devices—a firewall is represented by flames, for example. And the map reflects the true shape of the network design.

This is a map with problems

This map has a lot of black wires. The network looks flat, fragmented, and incomplete.

Check SNMP status

Auvik relies on SNMP to gather data from key devices on your network, such as routers, firewalls, switches, and Wi-Fi infrastructure. If a device doesn’t have SNMP enabled or the credentials aren’t entered correctly in Auvik, the map might not render correctly.

Go to Discovery > Manage Devices in Auvik’s side navigation bar to see a list of devices and their current SNMP status.

How to test whether SNMP is working

To test if SNMP works, you can use the Auvik collector to try an SNMPwalk on the device. This will tell you if SNMP is configured correctly and accepting SNMP queries from the Auvik collector. Please follow How do I debug using the Auvik collector to test if SNMP is working correctly.

Devices aren’t appearing on the map

Auvik uses ping (ICMP) to discover devices on your network. If a firewall or a router is blocking ICMP packets on a device, Auvik won’t be able to discover that device. To solve this issue, whitelist the Auvik collector’s IP address on your firewalls and routers.

To troubleshoot devices that aren’t appearing on the map, you can use the Auvik collector to perform a scan on a specified network. Devices that appear in the scan results should appear on the map.

If your device doesn’t reply, it may be in stealth mode and blocking pings (ICMP packets) from the Auvik collector. If so, add a policy to allow pings by the Auvik collector.

Devices have incorrect connections

Using the data collected through SNMP, Auvik tries to discover what each interface on a device connects to. Auvik also uses CDP and LLDP to determine connections. CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol) are protocols that switches use to advertise their identities, capabilities, and neighbors.

If Auvik has mapped connections incorrectly, first ensure that CDP or LLDP is enabled on your switches. Most devices have the protocols enabled by default, but it’s always good to check.

If enabling CDP or LLDP doesn’t correct the connection, you can manually change connections by editing the interface details.

Devices aren’t correctly classified

Auvik automatically classifies devices as they’re discovered. Auvik supports more than 7,300 devices from over 230 vendors. Still, there are times we encounter devices that aren’t on our list, which means we don’t have an object identifier record for that device.

Auvik isn’t authorized to log into devices

In addition to SNMP, Auvik uses SSH and Telnet to gather information on your network devices. (Some devices don’t give out enough information through SNMP so Auvik relies on SSH and Telnet to learn more.) Devices that are missing login credentials may not show up correctly on a network map.

If SSH or Telnet is already enabled, you may have to permit the Auvik collector to log into the device. Once you’ve verified that the Auvik collector is permitted to login, add the login credentials to Auvik.

If you can’t find your map issue on this list, or your map is still not displaying correctly after trying these fixes, contact Auvik support for further help.

Cisco ASA shunning the Auvik collector

If your Auvik collector is intermittently disconnecting from our servers or losing Internet connectivity altogether and you have a Cisco ASA on your network’s perimeter, the ASA may be >shunning> the Auvik collector as a result of aggressive threat detection. To stop the ASA from shunning the Auvik collector, see Known issue with Cisco ASA shunning Auvik collector.

Dynamic IP is causing fluctuations in the data

If the map is exhibiting odd behavior, redrawing itself, or displaying corrupted data, the Auvik collector may be getting its IP address using DHCP. To keep the data Auvik collects as consistent as possible, assign the virtual appliance a static IP or create a DHCP reservation.
